Turnbull, Netanyahu hold talks in Israel

Prime Minister Malcolm Turnbull insists Australia’s relationship with Israel has never been more profound than now in the face of Islamist terrorism after meeting with his Israeli counterpart Benjamin Netanyahu in Jerusalem.

Mr Turnbull was due to land on Saturday but delayed his visit to deal with the fallout from the High Court's decision to disqualify Barnaby Joyce from parliament.

But the leaders still don't see eye-to-eye on Iran despite lengthy discussion, with Mr Turnbull reiterating Australia's view to stick with the nuclear agreement which the Israelis want to end.

And the chaos at home invevitably followed Mr Turnbull to Israel; when asked if he had thought of just walking away from it all, Mr Turnbull smiled and replied: "I have never had more fun in my life".

Mr Netanyahu and Mr Turnbull, who later privately dined together with wives Sara and Lucy, both acknowledged the centenary of the Battle of Beersheba - which will be commemorated with a series of events later today.

Mr Turnbull described it as a pivotal moment in history, led by Australian horseman who - some on their own horses - helped liberate Palestine from the Ottoman empire.

"It was a great victory - the last successful calvary charge in military history and certainly one that rings through the ages," he said.

Mr Netanyahu labelled it the "gateway to the rebirth of the Jewish people".

"(It) would not have been possible without the heroism and sacrifice of Australian troops who liberated this land from 400 years of Ottoman rule with tremendous courage," he said.

Mr Turnbull insisted he has "never had more fun" despite the troubles facing his government at home, including the continuing fallout from losing two cabinet ministers.

Mr Turnbull had a tumultuous past week, with the High Court disqualifying Deputy Prime Minister Joyce and cabinet minister Fiona Nash over their dual citizenship and ructions over Employment Minister Michaelia Cash misleading parliament over raids on two Australian Workers Union offices.

"I know stories of turmoil are more likely to attract a click than good government, but the reality is government goes on, it's business as usual," he told reporters in.

When asked if he had thought of just walking away from it all, Mr Turnbull smiled and replied: "I have never had more fun in my life".

Trade Minister Steve Ciobo says the prime minister has a huge amount on his plate, but is taking the country in the right direction.
